Abstract

Disclosed is a process for the preparation of a solution containing glucose and fructose (isoglucose) by the conversion of a glucose-containing solution on a catalyst having glucose isomerase activity and produced on the basis of a SiO.sub.2 carrier. The productivity of the catalyst may be significantly increased by the addition of SiO.sub.2 to the glucose solution, and the catalyst according to the present invention is not damaged by temporary process shutdowns.
